YLIINOTYPE-NIACHINE.

To all whom it -may concern:

Be it known that I, WrNToN, GORDON Mn IDLETON, of Tucson, county of Pima, and Territory of Arizona, have invented a new and useful Im rovement in Linotype-Machines, of which t e following isa s eclfication. q

M invention relates to mo ds for li otype: mac 'nes wherein a slu or linotype typemetal is cast in a slotted mold against a com posed line of matrices. which forms the type characters on the edge of the slu as shown, for exam le, in Letters Patent 0 the United States NE; 436,532. chines it is frequently necessary to change the length of the slug produced according to the width of the page or column desired and alsonecessary to change the thickness of the slug in order'that it may carry type characters of-difi'erent sizes and that they may appear solid or leaded.

The princi al aim of myinvention is to rovide a mo (1 which may be instantly ad-" usted both as to length and as to width without the necessity of detaching or ap lying parts. 'In this class of machines thes ugsor llnotypes are ejected from the mold between kmves, which insure their uniformity in thickn s, and it is. of course necessarthat the distance between these knives sha 1 be varied according to the variations in the adjustment of the .mold and the consequent thickness of the slug produced. I therefore propose to combine with my adjustable mold an adjustable trimming-knife coo eratin with the mold in such manner. that t e mol effects the movement of the knife.

Referring to the drawings, Figures 1, 2,

and 3 are'pers ective views of my mold with the arts in ifierent positions to" ve the mol -slot different dimensions, the si eplates being broken to expose the internal' parts to view. Fi 4 is a ongitudinal vertical section showing a detail.v Fig. 5 is a longitudinal vertical section through another detail, hereinafter explained. Figs. 6, 7, and 8 are cross-sections on correspondingly-numbered lines of Figs. 1, 2, and 3. Fig. 9 is a front elevation illustrating the manner in which the moldand the trimming-knife interact to insure their corresponding adjustment. Fig. 10 is a cross-section of the same on the line 10 10.

Referring to the various drawin a represents the mold slot or cell in whic the slug is cast. This cell extends through the mol Specification of Letters Patent. Application filed larch 24,1906. Serial No.-80'l.8 05- In this class of ma- "C longitu "justed -to produce a ongs1 Patented Oct. 30, 1906.

from front to rear and is open on both sides,

so that matrices may be presented theretoon one side and molten metal delivered therein from the other side, as usual inlinotypemachines. I

The lower side of the mold slot or chamber is formed by a stationary bod portion A of the mold, having a suitable flat surface on the top. The upger side of the mold is formed by a mold-cap and which is adjustableboth longitudinally and vertically for a purpose to be presently ex lained. I s

.The vertical movement of the cap B dewhich overlies the body termines the height of the slot and the thickness of the slu formed therein. The left end of the mold-s ot is formed by the end of. a block 0, which is dovetailed to the-top of the body portion Ain order thatit mayslide lengthwisethereon to ya the le th of the mo d-slot'. The up er'si e of the lock C is grooved or channe ed 10 'tudinally to receive and 'hold the reduce ca i B, extending beyond the mold-slot.

\ he right end of the mold-slot is formed b the end of'a vertically-movable block D.

his block is slotted or recessed longitudiend of the moldnally to fit over the body ortion A, which is reduced to receive an guide it. The block D, which is without end motion, is also connected at its upper side by a longitudinal. dovetail .'oint d to the cap B, so that it may" rise and fall therewith.

' The length of the moldslot and of the slug is varied Iii-shifting the cap B and the bloc ally. 1 shows them adand Fig. 2

showsthem in position to pro uce ashorter slu - The height of the slot andthe consequent thickness of the slu are changed by raising .or lowering the bloc D and the mold-cap B. 'In Figs. 1 and 2 they are shown in position to produce a comparatively thin slug, while in ig. 3 they are shown raised to produce a thicker slug.

The cap B and the end block Dare urged constantly downward by a spring E, seated within the lower part ofthe block D and.

bearing upward against the under sideof the mold-body. The cap and block are raised to increase the height of the slotb two horizontally-moving wedges F and the former within the member C and acting against mold-cap and the latter seated on an inengagement.

clined surface in the body and acting beneath the upper part of the end block D. The simultaneous and equal movement of the two wedges to raise the cap B and the block or permit their descent is effected by a hand-lever G, pivoted between its ends to the body of the mold and jointed at its upper end to a bar or latch H, which is in turn pivoted at h to a horizontal bar I, guided in thebody of the mold. This bar is provided at one end with a slot i to'receive a projection'on the wedge F" and at the opposite end is provided with a latch t to engage a projection f on the under side of the wedge F,

this projection being also engaged when the parts are in normal position by the end of' the atch'H, as shown in Fig. 3. When the lever G-is moved in one direction, it carries the bar I to the right, thereby retracting the twowedges and permitting the mold-cap to de scend, thus reducing the height of the slot. When the lever is moved in the reverse direction, the wedges are advanced and the cap and end section B raised to increase the height of the slot and the thickness of the slu cast therein.

sector-plate J is secured to themoldbody and provided with graduations representing the various thicknesses of the slug-'- as agate, non areil, &c.sothat the operator guided thereby may instantly set the lever and adjust the mold for any body domanded. The lever G is provided with a sliding latch 9, one end of which is ada ted to enter holes in the sectorfplate for Ice 'ng the lever in its various positlons v The length of the mold-slot is varied by moving the mold-cap B and the sleeve or member C lengthwise in order to change the distance between. the members C and D. This longitudinal movement may be effected by hand or mechanically.

To prevent the movement of the wedge F and the consequent disturbance of the vertical adjustment duringthe lon 'tudinal movement, I mount on one edge of't e wedge F, as shown in Figs. 2, 5, &c., a verticallymovable latch K, having toothed edges to engage correspondingteeth is in the sides of the part C. This latch is urged downward by'aspring'k, Fi 5, and is held normally in When the vertical adjustment efiected, it is moved back to its extreme position at the left, as shown in Fig. 1,- and as the first step in effecting adjustment the latch K is lifted out of' engagement by the arm or lever H, connected to the verticaliy-movablelateh gon the handleverG. When this latch is depressed to engage the handl'e'ver, it draws down theadj a cent end of the lever or arm H, causing its opposite end to act beneath the latch K and of the cap is to be 6 5 disengage the same, as shown in Fig. 3', theresenses It may be provided, for example, with a ver-.

tical locking-pin L, extending through one of the series ber D.

The entire mold is mounted to slide endwise horizontally on the main frame, so that after the casting action it may be presented in front of the ejector-blade N by which the slug is ex elled from the mold between the trimmingknives, as showni O and P represent the two knives between which the slug is delivered. The'lower knife 0 is secured firmly to the frame, while the up er knife P is secured to' a vertically-movab esupport 1), guided at its ends in the frame and urged downward by springs 19. The up er surface of the mold-cap B is inclined rom the horizontal, and the under side of' the knife-support has a like inclination, so that as the mol d' advances tothe ejecting position it underrides the support fp and raises the-same, together with the kni e P, until the distance betweenthe knives corres ends with the thickness of the slug in the mo d whatever it may be.

It will be observed that the mold acts automatical l'y and positively to effect the retraction of' the movable knife, so that the distance between the knives wil'l correspond witlh the thickness of the slug produced in the mo d.

The essence of my invention as regards the mold lies in so connecting and arrangin the members which form the four sides 0 the mold cell or slot that the are relatively movable in order to permit the dimensions oi the slot to be varied both in height and in length, so that the length and thickness of the slug produced may be changed without the substitution of'li'ners or other parts of the mold. It wili be manifest to the skilled mechanic that the parts ma be widely modified inform, and the detai s of the connections and the adjustin devices may be modified without passing beyond the scope of my invention.

. Having described my invention, what 1'. claim is- 1. A linotype-mold comprising four permanently-connected members form-i the four walls of the slot, their relations ein variable, substantially as described an shown, tochange the length or the thickness of the slots; whereby the outcoming slugs may be-varied' as to length and thickness, or

of holes in the cap to. the memeither, without removing parts from orapplying parts to-the-mold.

2. In a linotype-mold, the combination of a body member, the longitudinally-movable end member C, the vertically-movable end member D, and the vertically and longitudinally adjustable cap'B.

3. In a slotted linotype-mold, the combination of a body portion, a cap ortion movable both vertically and longitu inally, and means for closing the two ends of the slot under the various adjustments of the cap.

41 In combination with the mold-body A, the vertically-movable member D, a moldcap connected to the membertD, by a longitudinal sliding joint, and the member C, connected to the body by a longitudinallysliding joint and also connected to the cap by a vertical joint.

5. In a linotype-mold, the combination of a body member, a rising and falling cap, a spring tending to depress the cap, wedges to effect the elevation of the same, and means for adjusting and locking the Wedges in predetermined positions, whereby the mold may be adjusted to produce linotypes of standard thicknesses.

6. In combination with the body member A, and cap B, the relatively movable end members 0, and D, the adjusting-wedges, means for moving the Wedges simultaneously, and means for locking the wedges in predetermined ositions.

7. In a inotype-mold, in combination with the body and members forming the ends of the mold-slot, the vertically-movable cap, a hand-lever, means connected therewith to eflect the vertical adjustment of the cap,

and means for locking the lever in predetersurface acted upon by the mold to determine the adjustment .of the knife.

10. In a linot pe-machine, a fixed knife, an opposing kni e movable to and from the first, springs tending to advance the movable knife toward its companion, and a movable mold acting to effect the separation of the knives.

11. In a linotype-machine, a slotted longi tudinally-reciprocating mold including a vertically-movable member to var the hei ht of the slot, in combination Wit a mova ,le slu -trimming knife controlled as to its position by the movable member-of the mold.

- In testimony whereof I hereunto set my hand, this 13th day of March, 1906, in the presence of two attestin witnesses.
